If you want a relatively quick way to make weighted but randomized decisions for your multi-player board games, I’d suggest checking out “The GameMaster’s Apprentice: Base Deck” on DriveThruRPG.

It’s a generic deck of solitaire supporting cards with a LOT of different random cues & ideas for running a narrative with some unforeseen events.

Originally made for creating solitaire RPG storytelling, some of the parts can also be used to make Bot-like decisions for strategy board games. Notably the weighted Yes/No questions, Random direction/scatter indicators, bell curve 1-10 random number gen, etc. Maybe even some leader behaviors/goals.

You’re also not stuck spending extra time rolling dice to decide, after formulating the question – just draw a card. Time saver.

I have no connection to the creators or sellers. Just a very handy solo gaming & storytelling tool with many uses. Thought you might think it useful since you often solo multi-player board games. 😉
